CROSS REFERENCE TO RELATED APPLICATIONS

The present application is a continuation application of International Application PCT/JP2016/078765, filed on Sep. 29, 2016, which claims priority to Japanese Patent Application No. 2015-192565, filed on Sep. 30, 2015, and of International Application PCT/JP2017/013025, filed on Mar. 29, 2017. The contents of these applications are incorporated herein by reference in their entirety.

FIELD OF THE INVENTION

The present invention relates to a nucleic acid derivative having immunostimulatory activity. In more detail, it relates to a double-stranded oligonucleotide wherein the first strand is a CpG oligonucleotide, and the second strand binds to a lipid.

BACKGROUND ART

A vaccine which is a medicine for infectious disease or cancer utilizes an antigen-specific immune response. An adjuvant is a compound having an immunostimulatory activity which is used to enhance efficacy or durability of a vaccine, and various kinds of adjuvants such as aluminum salt, emulsion and liposome have been researched or developed (Non-patent Document 1 or the like).

A single-strand oligodeoxynucleotide comprising a dinucleotide motif of unmethylated cytosine guanine (5′-CpG-3′) (ssCpG ODN) is known as a one of the adjuvants. ssCpG ODNs are ligands of TLR9 (Toll-like receptor 9), and extremely efficient inducers of Th1 immunity or cytotoxic T-lymphocyte (CTL) responses thorough TLR9 to stimulate the immune system (Non-patent Document 1). However, there are problems related to in vivo stability, toxicity, pharmacokinetics or the like of ssCpG ODNs to use alone. A method that ssCpG ODN is encapsulated in a nanoparticle made of lipid bilayer (Non-patent Document 2), a method that lipid binds to 5′ end of ssCpG ODN (Non-patent Document 3 or Patent Document 1) or the like is known as means for solving these problems.

Furthermore, it is known that the charactericity as an adjuvant was vanished when ssCpG ODN was administered as a double-stranded DNA (dsCpG ODN) by annealing the first strand and the second strand (Non-patent Document 4). Non-patent Document 5 discloses that only dsCpG ODN did not show the immunostimulatory activity, but when dsCpG ODN was encapsulated in a lipofectin particle, the dsCpG ODN comprising either CpG motif or GpC motif showed the immunostimulatory activity.

SUMMARY OF THE INVENTION Problems to be Solved by the Invention

The purpose of the present invention is to provide new nucleic acid derivatives having immunostimulatory activity which are useful as an adjuvant of a vaccine and/or a vaccine itself.

Means for Solving the Problem

Non-patent Documents 4 and 5 disclose that administering dsCpG ODN did not show the immunostimulatory activity. Furthermore, Non-patent Document 5 discloses that when dsCpG ODN was encapsulated in a lipofectin particle, the dsCpG ODN comprising either CpG motif (ODN4531) or GpC motif (ODN4531GC) induced IL-8 and HLR-DRA expression, that is, by a method which is independent of a CG sequence. It suggested based on the fact that dsCpG ODN was rapidly degraded in cells compared to ssCpG ODN that the reason why dsCpG ODN encapsulated in a lipofectin particle showed immunostimulatory activity is that encapsulation of dsCpG ODN may protect against rapid degradation (page 167, the right column, lines 10 to 16).

The present inventors have intensively studied to synthesize a double-stranded oligonucleotide (a lipid binding double-stranded oligonucleotide of the present invention) wherein a first strand is a CpG oligonucleotide, and a second strand is an oligonucleotide comprising a sequence capable of hybridizing with the first strand and binds to a lipid. They found that the inducibility of antigen-specific CTL by a vaccine was enhanced and showed the anti-tumor effect by administering a lipid binding double-stranded oligonucleotide of the present invention as an adjuvant with a tumor antigen peptide (when a lipid binding double-stranded oligonucleotide of the present invention is used as an adjuvant, it is also referred as “an adjuvant of the present invention”). In addition, they found that there is a lipid binding double-stranded oligonucleotide in the present invention which shows strong anti-tumor effect by itself, that is, which is useful as a cancer vaccine (when a lipid binding double-stranded oligonucleotide of the present invention is used as a vaccine, it is also referred as “a vaccine of the present invention”). That is, a lipid binding double-stranded oligonucleotide of the present invention has the immunostimulatory activity. Furthermore, lipid binding double-stranded oligonucleotides of the present invention have high metabolic stability, water solubility and less toxicity to be safe enough as a medicine.

For example, when an adjuvant of the present invention wherein the second strand is a DNA oligonucleotide, an oligonucleotide consisting of nucleoside derivatives having OMe at the 2′ position of the sugar or an oligonucleotide consisting of nucleoside derivatives having F at the 2′ position of the sugar was administered with a tumor antigen peptide, they showed the enhanced CTL inducibility or the strong anti-tumor effect compared to ssCpG ODN (e.g., Result 1-A, B, Result 7-A, B and Result 9-A, B in Example 3). On the other hand, the lipid binding double-stranded oligonucleotide wherein the second strand is a RNA oligonucleotide (SEQ-40) did not show the anti-tumor effect (Result 7-B).

When an adjuvant of the present invention wherein a lipid comprising two of the acyl chains having 14 to 24 carbon atoms binds at 3′ or 5′ end of the second strand was administered with a tumor antigen peptide, it showed the strong anti-tumor effect compared to ssCpG ODN (e.g., Result 2-A, B in Example 3). On the other hand, when a double-stranded oligonucleotide wherein a lipid comprising two acyl chains having 10 carbon atoms binds at 5′ end of the second strand (SEQ-12) was administered with a tumor antigen peptide, it did not show the enhanced anti-tumor effect compared to ssCpG ODN. In addition, when an adjuvant of the present invention wherein a lipid comprising two of the acyl chains having 12 to 20 carbon atoms binds at 3′ or 5′ end of the second strand, and furthermore a lipid binds at the other end was administered with a tumor antigen peptide, it showed the enhanced CTL inducibility or the strong anti-tumor effect compared to ssCpG ODN (e.g., Result 3-A, B in Example 3).

When an adjuvant of the present invention wherein the length of the second strand is 50% to 100% of that of the first strand (the CpG oligonucleotide) was administered with a tumor antigen peptide, it showed the enhanced CTL inducibility or the strong anti-tumor effect compared to ssCpG ODN (e.g., Result 4-A, B, Result 5-A, Result 8-A, B, and Result 9-A, B in Example 3).

When an adjuvant of the present invention wherein a lipid binds to a second strand through an oligonucleotide linker (e.g., dGdG, dTdT and dAdA) was administered with a tumor antigen peptide, it showed the further enhanced CTL inducibility or the stronger anti-tumor effect compared to an adjuvant of the present invention without a linker (e.g., Result 8-A, B in Example 3).

In addition, lipid binding double-stranded oligonucleotides of the present invention have no systemic toxicity, and it suggested the high safety (Example 5).

Furthermore, the result of immunization with an adjuvant of the present invention and PCRV protein derived from Pseudomonas aeruginosa which is a cause of an infectious disease also suggested the immunostimulatory activity as an adjuvant of a vaccine for an infectious disease (Example 6).

When the adjuvant of the present invention wherein lipid binds to a second strand through an oligonucleotide linker (dGdGdGdGdG) (SEQ-121) was administered alone, it showed the strong anti-tumor effect compared to ssCpG ODN (Example 4).

A first strand of a lipid binding double-stranded oligonucleotide of the present invention is a CpG oligonucleotide consisting of 8 to 50 nucleotides.

The “CpG oligonucleotide (CpG ODN)” means a single-stranded oligonucleotide comprising dinucleotide of non-methylated cytosine guanine (5′-CpG-3′) motif (CpG motif) and it is well known that it can be useful as a vaccine adjuvant because it induces acquired immune response through TLR9 (Nat Rev Drug Discov, 2006, 5, 471-484, Expert Rev Vaccines., 2011, 10(4), 499-511). The CpG oligonucleotide used for the present invention comprises at least one CpG motif and may comprise several CpG motifs.

ODN1826 or ODN2006 is especially preferable.

A second strand of a lipid binding double-stranded oligonucleotide of the present invention is an oligonucleotide consisting of 8 to 60 nucleotides and comprising a sequence capable of hybridizing with the CpG oligonucleotide which is the first strand, but excluding a RNA oligonucleotide,

Preferably, a second strand is an oligonucleotide consisting of 8 to 60 nucleotides and comprising a sequence capable of hybridizing with the CpG oligonucleotide which is a first strand under a stringent condition.

Any oligonucleotide can be used for a second strand as long as it can be hybridized with the CpG oligonucleotide under a stringent condition, and the one comprising 1 or several mismatch(es) in a part of hybridization can be exemplified.

For example, it is the oligonucleotide whose part for hybridization has at least 70% or more, preferably 80% or more, more preferably 90% or more, and most preferably 95% or more homology to a complementary sequence of the CpG oligonucleotide of a first strand.

The homology shows the similarity as a score, for example, by BLAST, a search program using algorithm discovered by Altschul et al. (The Journal of Molecular Biology, 215, 403-410 (1990).)

The “stringent conditions” mean conditions under which a base sequence forms hybrid (so-called specific hybrid) with a specific sequence but any base sequence without the equivalent function does not form hybrid (so-called non-specific hybrid) with the specific sequences. People skilled in the art can easily select the conditions by changing a temperature during hybridization reaction or washing, salt concentration in hybridization or washing buffer, or the like. In detail, an example of the stringent conditions of this invention is, but not limited to the condition, which the oligonucleotide is hybridized in 6×SSC (0.9 M NaCl, 0.09 M trisodium citrate) or 6×SSPE (3 M NaCl, 0.2 M NaH2PO4, 20 mM EDTA.2Na, pH 7.4) at 42° C. and washed with 0.5×SSC at 42° C. As a hybridization method, well-known methods in the art, for example, southern blot hybridization or the like can be used. In detail, it can be performed according to a method disclosed in Molecular Cloning: A Laboratory Manual, Second Edition (1989) (Cold Spring Harbor Laboratory Press), Current Protocols in Molecular Biology (1994) (Wiley-Interscience), DNA Cloning 1: Core Techniques, A Practical Approach, Second Edition (1995) (Oxford University Press) or the like.

“1 or several mismatch(es)” means 1 to 5, preferably 1 to 3, and more preferably 1 or 2 mismatches.

The length of a second strand of a lipid binding double-stranded oligonucleotide of the present invention is 8 to 60 nucleotides. For example, it is 8 to 60 nucleotides, 8 to 50 nucleotides, 8 to 40 nucleotides, 8 to 30 nucleotides, 10 to 25 nucleotides or 15 to 25 nucleotides. The length of the second strand can be same with that of the CpG oligonucleotide which is a first strand, and 1 or several nucleotide(s) shorter than that of the CpG oligonucleotide as long as it can be hybridized with the CpG oligonucleotide. Furthermore, the length of a second strand can be longer than that of the CpG oligonucleotide by adding 1 or several nucleotide(s) at one or both sides of a part hybridizing with the CpG oligonucleotide.

“1 or several nucleotide(s)” means 1 to 10, 1 to 5, 1 to 3, or 1 or 2 nucleotide(s).

A preferable length of a second strand depends on the length of the CpG oligonucleotide of a first strand. For example, it is a length of 50% or more, 60% or more, 70% or more, 50 to 100%, 60 to 100% or 70 to 100% of the length of a first strand. 50 to 100% of the length of a first strand is especially preferable.

All nucleosides can be same, or two or more kinds of nucleoside. However, an RNA oligonucleotide which all nucleosides are a RNA nucleoside is excluded. As a nucleoside comprised in a second strand, an oligonucleotide which DNA nucleosides and/or nucleoside derivatives are bounded is preferable. All nucleosides can be a DNA nucleoside, nucleoside derivative, or both of them.

When an oligonucleotide comprises DNA nucleosides and nucleoside derivatives, an example is an oligonucleotide comprising a center region and end regions at the both sides of the center region, and comprising at least one nucleoside derivative in the end region at the both sides. In detail, 5′ and/or 3′ end region(s) comprises 1 or more, preferably 1 to 5, and more preferably 2 to 3 nucleoside derivatives. The kind, number and position of modification(s) in one end region may be same or different from those in the other end region. In the other embodiment, it is an oligonucleotide randomly comprising nucleoside derivatives.

As a nucleoside derivative in a second strand of a lipid binding double-stranded oligonucleotide of the present invention, any modification(s) for a nucleoside which is well-known in this field such as the above examples can be used.

For example, 5′ and/or 3′ end region(s) comprises 1 or more, preferably 1 to 5, and more preferably 2 to 3 unnatural internucleoside linkages. The kind, number and position of modification(s) in one end region may be same or different from those in the other end region. In the other embodiment, it is an oligonucleotide randomly comprising unnatural internucleoside linkages.

The CpG oligonucleotide of a first strand and oligonucleotide of a second strand in a lipid binding double-stranded oligonucleotide of the present invention can be synthesized according to the usual methods in this field. For example, they can be easily synthesized by an automated nucleic acid synthesizer which is commercially available (e.g., the synthesizer by AppliedBiosystems, Dainippon Seiki and GE Healthcare). A method for synthesizing is solid-phase synthesis using phosphoramidite, solid-phase synthesis using hydrogen phosphonate or the like. Examples are disclosed in the following Example 1, Tetrahedron Letters 22, 1859-1862 (1981) and the like.

As a lipid used for the present invention, a lipid comprising a hydrocarbon chain(s) is preferable. Preferably, it is a lipid comprising 1 or 2 hydrocarbon chain(s) or the like. Especially preferably, a lipid binding double-stranded oligonucleotide of the present invention has a diacyl lipid.

A monomer was prepared in 0.1 M acetonitrile solution using the amidite derived from the above amidite synthesis. The coupling time was 32 seconds to 10 minutes, and 8 to 10 equivalents of the amidite unit were used to condense with one monomer. 0.02 M Oxidizer (Sigma-Aldrich) and iodine/pyridine/water/=12.7/9/1 (w/v/v) were used for PO oxidation. 50 mM DDTT ((dimethylamino-methylidyne) amino-3H-1,2,4-dithiazoline-3-thion) in acetonitrile/3-picoline 1/1(v/v) or 1/4(v/v) and acetonitrile/pyridine 1/4 (v/v) solution were used for PS oxidation. ETT activator (5-ethylthio)-1H-tetrazole) (Sigma-Aldrich) was used as an activator, CapA and CapB (Sigma-Aldrich) was used as a capping reagent. Deb (3 w/v % TCA CH₂Cl₂ solution) (Wako Pure Chemical Industries, Ltd.) or Deb (3 w/v % Dichloroacetic acid, Toluene Solution) was used as a detritylation reagent.

DMT-butanediol phosphoramidite used for synthesis of SEQ-316 were purchased from ChemGenes Corporation.

C) Synthesis of Lipid-Binding Oligonucleotides

1) Preparation of Lipid-Binding Oligonucleotides from the Synthesized Amidite Unit Described Above

A stirrer, Molecular Sieves 4A 1/16 and the amidite synthesized in the above A) (e.g., Compound 4-n, Compound 4-n,o, Compound 8-n and Compound 10-n. 10 to 100 equivalents of an oligonucleotide) were put in a microwave tube (2-5 ml, 10-20 ml) made by Biotage, and the solution was adjusted to 0.2 M with chloroform (added 2-methyl-2-butane as a stabilizer). After drying for 5 hours, a oligonucleotides supported to solid phase (CPG resin or polystyrene resin) and 0.25 M ETT activator, which is ((5-ethylthio)-1H-tetrazole) dichloromethane (the same amount of chloroform) were added, sealed and heated at 40° C. for 10 minutes to 1 hour. After cooling to room temperature, the reaction mixture was diluted twice with chloroform, and the resin was collected by filtration. The resulting resin was used in PS oxidization in NS-8-I (Dainippon Seiki co., ltd.) or NS-8-II (Dainippon Seiki co., ltd.). Then the dried resin was subject to the following deprotection condition I or II to synthesize the target lipid-binding oligonucleotide.

2) Synthesis from Lipid-Supported Resin

Using a resin supported lipid synthesized in the above A) (e.g., Compound 15-n, Compound 22-n, Compound 50-n, Compound 51-n, Compound 55 and Compound 63-n), the target lipid-binding oligonucleotides were synthesized in a similar method to the above B).

D) Deprotection

For cutting out DNA oligonucleotide, 28% ammonia water (SEQ-1, 3 or 49) or 28% ammonia water/EtOH4/1(v/v)(Single strand oligonucleotides described in Examples except for SEQ-1, 3 and 49) was used and the solution was shaken at room temperature for 1 hour and at 55° C. for 5 hours. 1 ml, 5 ml or 10 ml of ammonia solution was used for 1 μmol, 5 μmol or 10 μmol synthesis, respectively, for cutting-out reaction. After the resin was washed with 50% ethanol water, the filtrate was concentrated under reduced pressure to about 1 to 5 mL.

When the sequence contains RNA, the resulting solution was lyophilized to obtain white powder, and then the following deprotection reaction of the 2′-TBS group was performed.

2) Deprotection of 2′-TBS Group

To the resulting white powder, N-methylpyrrolidone/triethylamine/triethylamine trihydrofluoride=6/1/2(v/v) was added and the solution was stirred at 65° C. for 1.5 hours. To the reaction mixture was added the same amount of ethoxytrimethylsilane, and the solution was vigorously stirred at room temperature for 10 minutes to obtain the precipitate. After centrifugation at 2500×g (2 minutes), the organic solvent layer was carefully removed. To the resulting precipitate, diethyl ether was added, and the solution was vigorously stirred. Then, in a similar way, the centrifugation was carried out and removed the organic solvent to obtain crude RNA unit (white solid).

Example 2 Activity Evaluation of Lipid Binding Double-Stranded Oligonucleotides of the Present Invention Using the Reporter Assay (Materials and Methods)

HEK-Blue™ hTLR9 cells (Invivogen) used for the reporter assay were made by introducing human TLR9 gene and a reporter gene that secretory alkaline phosphatase gene bound to NF-kB⋅AP-1 binding region sequence in HEK293 cells, and are the cells stably expressing the both genes. 3.6×10⁴ of the cells suspended in HEK-Blue™ Detection (Invitrogen) comprising substrates against the alkaline phosphatase were seeded on the 96 well plate, and 3 nM to 30 μM of a lipid binding double-stranded oligonucleotide of the present invention, the known CpG oligonucleotides (ODN2006, SEQ-49), or adjuvant based on design in Patent Document 1, i.e., ssCpG ODN introducing a lipid ligand (SEQ-142, 143 or 144) was added. After culturing in a 37° C., 5% CO₂ incubator for 16 hours, absorbency at 620 nm was measured using the culture supernatant developed a color. The result value was analyzed with TIBCO Spotfire software, and calculated the 50% effective concentration (EC₅₀) of each oligonucleotide.

(Result)

As previously described, it is known that the charactericity as an adjuvant was vanished when ssCpG ODN was administered as a double-stranded DNA (dsCpG ODN) by annealing the first and second strand (Non-patent Document 4). To examine that the adjuvant design of double-stranded nucleic acid shows an activity as a TLR9 agonist, activity evaluation of a double-stranded oligonucleotide was carried out by a reporter assay.

As shown in Table 28 and 29, ODN2006 (SEQ-49) which is a ssCpG ODN showed the activity as a TLR9 agonist, and the EC₅₀ value was about 467 nM (Experiment 1, Table 28) and about 245 nM (Experiment 2, Table 29). On the other hand, a lipid binding double-stranded oligonucleotide of the present invention comprising ODN2006 as a CpG oligonucleotide showed TLR9 agonist activity at a range of several tens to one thousand and several hundred nM. Most adjuvants of the present invention described in Table 28 and 29 had a tendency to enhance the activity compared to ODN2006. In addition, 16 sequences of SEQ-57, SEQ-59, SEQ-61, SEQ-63, SEQ-65, SEQ-111, SEQ-117, SEQ-135, SEQ-146, SEQ-226, SEQ-282, SEQ-284, SEQ-294, SEQ-324, SEQ-361 and SEQ-363 had a tendency to slightly lower the activity compared to ODN2006, but the difference was about 3 times. Therefore, it became clear that all lipid binding double-stranded oligonucleotides of the present invention have activity as a TLR9 agonist.

Furthermore, to examine that the modification form of SEQ-2 disclosed in Patent Document 1 applied for ODN2006 which is the human type CpG oligonucleotide sequence shows an activity as TLR9 agonist, activity evaluation was carried out in the same manner (SEQ-141, 142 or 143). SEQ-142, 143 or 144 could not induce the activation of TLR9 in the measured concentration range, and it was impossible to calculate the EC₅₀ values (n.d. in Table 28). That is, it is suggested that design (ssCpG ODN introducing a lipid ligand) disclosed in Patent Document 1 cannot be useful as an adjuvant of vaccine and/or vaccine itself because it showed the activity for ODN1826 (mouse type) but did not for ODN2006 (human type) as described in the example.

In contrast, it is suggested that a lipid binding double-stranded oligonucleotide of the present invention can be useful as adjuvant of vaccine and/or vaccine itself regardless of the sequence of the CpG oligonucleotides because it showed the activity for ODN2006 as well as ODN1826.

For analysis, after DAPI negative fraction was gated, white blood cells fraction were provided using forward and side-way scattering as indicators. In the white blood cells fraction, both positive cells of Alexa 647-CD8 and PE-H-2Kb Tetramer were defined as CTLs. CTL ratio in white blood cells was used for evaluation.

Calculation Method of the Indicator of CTL Inducibility

After calculation of the average CTL inducibility of each group per experiment, the ratio against average value of CTL inducibility of ssCpG ODN, ODN1826 (SEQ-1) or ODN2006 (SEQ-49) as a control was calculated.

In the case of an adjuvant comprising ODN1826 (Average of CTL inducibility of the adjuvant group)/(Average of CTL inducibility of the ODN1826 group)=the ratio against average value In the case of an adjuvant comprising ODN2006 (Average of CTL inducibility of the adjuvant group)/(Average of CTL inducibility of the ODN2006 group)=the ratio against average value

CTL inducibility of each adjuvant was shown when CTL inducibility of ssCpG ODN was taken as 1, so the bigger value means the higher CTL inducibility.

B) Evaluation of Anti-Tumor Effect of TRP2 Peptide Vaccine Using an Adjuvant of the Present Invention

After immunization by TRP2 peptide vaccine, B16F10 cells (ATTC) which is mouse melanoma expressing TRP2 protein was subcutaneously transplanted to evaluate anti-tumor effect. In a similar method to Example 3 A), on the next day that tetramer-positive ratio in peripheral blood of mouse vaccinated twice every 7 days was observed, B16F10 cells (1×10⁵ cells/mouse) were subcutaneously transplanted in the right shoulder. The major and minor axes of the engrafted tumor were measured every 2 to 3 days, and the tumor volume was calculated by the formula:

(major axis×minor axis²)/2

Calculation Method for Indicators of Anti-Tumor Effect

For the adjuvant comprising ODN1826 100−(average tumor volume of adjuvant group)/(average tumor volume of ODN1826 group) For the adjuvant comprising ODN2006 100−(average tumor volume of adjuvant group)/(average tumor volume of ODN2006 group)

The compound with bigger value has the stronger anti-tumor activity.

Result 1-A: Comparison of CTL Inducibility Between an Adjuvant of the Present Invention and the Known Adjuvants

When mice were immunized with TRP2 peptide and ODN1826 (SEQ-1), TRP2-specific CTL was induced. When dsCpG ODN (SEQ-4) was used, TRP2-specific CTL inducibility was lowered at 0.46 times compared to ODN1826. That is, double strands led to lower the CTL inducibility compared to a single-strand adjuvant. This suggested that when the CpG oligonucleotide is just made as a double-stranded form, the immunostimulatory activity is lowered as disclosed in Non-patent Document 4 and the like. On the other hand, when an adjuvant of the present invention, i.e., lipid binding double-stranded oligonucleotide adjuvant (SEQ-16) was used for immunization, the CTL inducibility was enhanced at 1.46 times compared to ODN1826. Therefore, it suggested that an adjuvant of the present invention has unexpected enhancement of activity. The results were shown in Table 31.

CTL inducibility and tumor inhibition rate of SEQ-12 (10 carbon atoms) was lowered compared to ODN1826 (SEQ-1). On the other hand, there is tendency to enhance CTL inducibility as the chain length is longer like SEQ-14 (14 carbon atoms), SEQ-6 (18 carbon atoms) and SEQ-16 (20 carbon atoms). In addition, tumor inhibition rate of SEQ-14 showed about 94% inhibition of the tumor growth compared to ODN1826 on Day 14 after transplantation, and SEQ-6 and SEQ-16 perfectly inhibited the tumor growth on Day 14 after transplantation. The results were shown in Table 32.

In a double-stranded oligonucleotide adjuvant design, it is necessary to release the CpG oligonucleotide, which is an active ingredient, in the lymph nodes. The speed to dissociate a double strand is proportionate to the heat stability, and the more complementary sites in the double strand structure are, the more stably the double strand exists.

Example 5 Irritation Test in a Single Dose of Adjuvants of the Present Invention A) Subcutaneous Irritation Test in a Single Dose

Subcutaneous irritation of a compound of the present invention was evaluated by gross examination and histopathological examination about the skin at necropsy one day, one and four week(s) after subcutaneous administration in a single dose.

The compound of the present invention was subcutaneously administered to the center of back between the shoulder blades of rats. At necropsy one day, one or four week(s) after administration (isoflurane anesthesia, euthanasia by bleeding), skin at the administration site was collected, grossly observed and fixed in 10% neutral buffered formalin solution. The fixed skin was cut out, embedded and put in a thin slice by the usual methods, and Hematoxylin-eosin (HE) stained sections were made. The pathological observers were observed the HE stained sections by an optical microscope, and recorded the histopathological findings. The changes in pathological findings were evaluated in four grades of Minimal; ±, Mild; +, Moderate; 2+ and Marked; 3+. When any grade was not appropriate for the finding, it was recorded as Positive.

(Result)

To verify the safety of adjuvants of the present invention as a medicine, the subcutaneous irritation was compared to that of Montanide used in clinical trials as an adjuvant, Amph1826 (SEQ-2) or ODN2006 (SEQ-49) which is the well-known adjuvant.

Montanide is an adjuvant consisting of mineral oil and surfactant, and used in clinical trials as an adjuvant of peptide vaccine by preparation of emulsion with aqueous formulation. Although it is an adjuvant with excellent safety profile about systemic safety concerns, there is a problem about the occurrence of skin induration caused by remaining emulsion in the administration site. In this experiment, the administration site reaction of the double-stranded oligonucleotide was compared to that of Montanide, and it was examined whether it could be an adjuvant with week local irritation.

Rat subcutaneous irritation tests in a single dose were carried out for Montanide, SEQ-2, SEQ-49 or an adjuvant of the present invention (SEQ-61, SEQ-119, SEQ-121, SEQ-170, SEQ-192 or SEQ-216). Montanide was administered at 1 mL/site in emulsion of Montanide: saline (1:1). SEQ-2, SEQ-49 or an adjuvant of the present invention was dissolved in phosphate buffered saline and administered at 4.71, 15.7 or 47.1 nmol/lmL/site, respectively.

As a result, it became clear that Montanide was not absorbed/decomposed/eliminated because white accumulation or white nodules was grossly observed under the skin and cyst-like structures was histologically confirmed one day, one and four week(s) after administration. Montanide remaining under the skin continued eliciting inflammation from one day to four weeks after administration. One day after administration, neutrophil infiltration and edema were observed. One week after administration, neutrophil infiltration and edema continued, but the inflammation became slightly chronic to observe as granulomatous inflammation. Four weeks after administration, thick fibrous capsule encapsulated Montanide was formed. Inflammation was slightly reduced compared to one week after administration, but even four weeks after administration, the animals with continuous neutrophil infiltration or edema were observed.

In the case of SEQ-2, inflammation cellular infiltration, edema and crust were observed one day and one week after administration. Even four weeks after administration, skin inflammation was not recovered, and granulomatous inflammation by continuous activation of monocyte/macrophage system was observed.

In the case of SEQ-49, and SEQ-61, SEQ-119, SEQ-121, SEQ-170, SEQ-192 and SEQ-216, which is an adjuvant of the present invention, acute inflammation, mainly neutrophil infiltration, was observed under the skin one day after administration. One week after administration, inflammation, mainly lymphocyte and macrophage, was observed from subcutaneous to dermis tissue, and four weeks after administration, inflammation was almost recovered. Regarding SEQ-119, SEQ-121 and SEQ-170, subcutaneous irritation evaluation four weeks after administration was not carried out, but when their subcutaneous irritation one day and one week after administration were compared to those of SEQ-119, SEQ-121, SEQ-170 and SEQ-61, the irritation were equal to or weaker than SEQ-61. These suggested that regarding SEQ-119, SEQ-121 and SEQ-170, inflammation was almost completely recovered four weeks after administration.

Tables 70 to 72 showed the results one day after administration, Tables 73 to 75 showed the results one week after administration, and Tables 76 and 77 showed the results four weeks after administration. The notes in the tables are as below.

1) Values after findings are numbers of the observed animals.

2) Values after findings are scores. The scores were calculated the total, provided that grades of each individual were put as Minimal; 1, Mild; 2 and Moderate; 3.

The above showed that compared between adjuvants of the present invention and Montanide, adjuvants of the present invention did not cause the accumulation of the compounds under the skin (low risk of induration), necrosis or neutrophil infiltration was not occurred even one week after administration, and inflammation was almost completely recovered four weeks after administration. Therefore, it was concluded that subcutaneous irritation of the adjuvants of the present invention was weaker than that of Montanide. Also, compared between adjuvants of the present invention and Amph1826 (SEQ-2), inflammation caused by adjuvants of the present invention was almost completely recovered four weeks after administration, but on the other hand skin inflammation caused by SEQ-2 was not recovered, and granulomatous inflammation by continuous activation of monocyte/macrophage system was observed even four weeks after administration. Therefore, it was concluded that subcutaneous irritation of the adjuvants of the present invention was weaker than that of SEQ-2. Subcutaneous irritation of adjuvants of the present invention was no significant difference from that of ODN2006 (SEQ-49).

B) Intradermal Irritation Test in a Single Dose

Subcutaneous irritation of adjuvants of the present invention of the present invention is evaluated by gross examination and histopathological examination about the skin at necropsy one day, one and four week(s) after subcutaneous administration in a single dose.

An adjuvant of the present invention is subcutaneously administered to skin of back of rats. The following procedure is carried out in a similar method to A) of Example 5.

Example 6 Evaluation of Inducibility of Antibody Production of the Adjuvant of the Present Invention in Immunization by Pseudomonas aeruginosa PCRV Antigen Vaccine

When antigen and adjuvant are administered as an infectious disease vaccine and induced antibody production from B lymphocyte in the immunized animal, effect of prevention and treatment for infectious disease is expected. Therefore, in expectation of apply for an infectious disease vaccine of this adjuvant, and antibody production from B lymphocyte was evaluated. PCRV antigen which is Pseudomonas aeruginosa was used for the examination as an antigen. It has been already reported that Pseudomonas aeruginosa PCRV antigen have a vaccine effect (Moriyama et al., Infect. Immun., September 2001, vol. 69, no. 9, 5908-5910), and therefore effect of inducibility of antibody production by the adjuvant was evaluated compared to PCRV antigen administration group. Freund's adjuvant was used for a control group. Freund's adjuvant is an adjuvant that tubercle bacillus killed by heating is mixed in oil consisting of paraffin oil and mannide monooleate, and known as an adjuvant strongly inducing antibody production in non-clinical studies. Freund's adjuvant shows strong effect in non-clinical studies, but the use in clinical trials has been prohibited because of concern of side effects (The European Agency for the Evaluation of Medical Products Evaluation of Medicines for Human Use, 25 Mar. 2004, Internet (URL: http://www.ema.europa.eu/docs/en_GB/document_library/Scientific_guideline/2009/11/WC500015469.pdf)).

Pcrv nucleotide sequence (SEQ ID NO: 48) derived from Pseudomonas aeruginosa Strain PAO1 was cloned at NdeI-XhoI site in pET21a vector, and Escherichia coli strain BL21 (DE3) was transformed with the prepared plasmid. Strain pcrV-BL21 (DE3) was cultured in 500 mL of LB/Ampicillin liquid medium at 37° C., and 200 μL of 0.1 M IPTG was added when OD600 became 0.5 to induce expression of recombinant PCRV protein. After culturing at 16° C. for 18 hours, bacteria was separated by a centrifuge, and 15 ml of Buffer A (50 mM Tris-HCl (pH8.0), 0.2M NaCl) comprising 0.5% lysozyme (SIGMA Corporation) was added. After putting at 4° C. for 30 minutes, ultrasonic treatment was carried out. After centrifugation at 12,000 rpm for 10 minutes, soluble fraction was obtained. 1 mL of Ni-NTA agarose gel (QIAGEN) was added to Polyprep column (BIO-RAD Laboratories, Inc) and equilibrated with 10 mL of Buffer A. Soluble fraction was added to the column and passed. The column was washed with 20 mL of Buffer A+20 mM imidazole and eluted with 1 mL of Buffer A+250 mM imidazole. Superdex 200 16/60 GL column was connected to AKTA Explorer (GE Healthcare), and equilibrated with 1.5 CV of Buffer A. The fraction eluted with imidazole was purified by gel filtration and recombinant PCRV protein C-end HIS (SEQ ID NO: 49) was purified. The resulting recombinant PCRV protein was measured the concentration with BCA assay kit (PIERCE) and kept at −80° C.

70 μg of recombinant PCRV protein and 33 nmol of an adjuvant of the present invention were mixed with saline to be 0.7 mL. To each 5 mice of 5 weeks old female A/J mice (Japan SLC, Inc.), 0.1 mL of immunogen was intradermally injected on Day 0, 7 and 27. As a control, only recombinant PCRV protein was used for immunization in a similar method. Regarding Freund's adjuvant, 100 μg of recombinant PCRV protein was mixed with saline to be 0.5 mL, and emulsion was prepared with the same amount of Complete Freund's adjuvant (Difco Laboratories). 0.1 mL was intradermally injected on Day 7 as initial immunization. On Day 27, Incomplete Freund's adjuvant (Difco Laboratories) was used for immunization in a similar method. On Day 33, blood was collect using a heparin from tail vein of mice, and centrifuged at 6,000 rpm for 15 minutes. The supernatant was collected as an antiserum and kept at −40° C.

Antibody titer was measured as blow. Recombinant PCRV protein was mixed with PBS (pH7.4) (Invitrogen) to be 1 μg/mL, and 20 μL/well of the solution was added to Nunc Maxisorp 384 well plate (Thermo). The plate was sealed with a plate seal and incubation was carried out at 4° C. over night. After washing twice with 90 μL/well of Washing Buffer (9 g/L NaCl, 0.5 g/L Proclin 150, 0.1 g/L Tween-20), 60 μL/well of 1× Assay Buffer (Invitrogen) was added. The plate was sealed with a plate seal and blocking was carried out at room temperature for 2 hours. After removing the liquid by tapping, antiserum was diluted with 1× Assay Buffer at 10³ to 10⁷ times and 20 μL/well of the solution was added. The plate was sealed with a plate seal and incubation was carried out at 4° C. over night. After washing three times with Washing Buffer, GOAT Anti-mouse IgG Fc-HRP (JacksonImmunoResearch) was diluted at 20,000 with 1× Assay Buffer and 20 μL/well of the solution was added. The plate was sealed with a plate seal and incubation was carried out at room temperature for 2 hours. After washing three times with Washing Buffer, 20 μL/well of TMB substrate (Dako) was added and incubation was carried out at room temperature for 30 minutes. 20 μL/well of 0.5 N sulfuric acid (Nacalai) was added, and absorbance at 450 nm was measured with a plate reader. The dilution ratio when absorbance at 450 nm is 1.0 was calculated and put as an antibody titer. The results were shown in FIG. 15.

The antibody titers were 3.0×10⁶ for SEQ-121 which is the highest, 2.5×10⁶ for Freund's adjuvant, 7.1×10⁵ for SEQ-61 and 5.3×10⁵ for ODN2006 (SEQ-49) in order. The antibody titer for only PCRV protein was 1.3×10⁵. These results suggested that the adjuvants of the present invention have strong immunostimulatory activity against B cells. Especially, antibody titer for SEQ-121 showed higher inducibility of antibody production than ODN2006 and almost same with antibody titer for Freund's adjuvant. Then, it was suggested that adjuvants of the present invention are excellent as an adjuvant for vaccine against infectious diseases. From these results, the adjuvants of the present invention are expected to apply for a vaccine against infectious diseases.
